Earthing & Lightning protection system with Early Streamer Emission Air Terminal

Need for Protection,The need for earthing & lightning protection is determined according to many parameters including the lightning flash density of the considered area. A risk analysis method . The lightning flash density or by local data including for example detection network, maps and statistics.

General principles : An Early Streamer Emission Air Terminal (ESEAT) is composed of one striking point, emission device and a fixing element and a connection to the down-conductors. The area protected by an ESEAT is determined according to its efficiency . The ESEAT should preferably be installed on the highest part of the structure. It shall be the highest point within the area to be protected.
